To maintain forward flight, the rotor tip-path plane must be tilted forward to obtain the necessary horizontal thrust component from the main rotor. By doing this, it causes the nose of the helicopter to lower which in turn will cause the airspeed to increase.
The wind from a running helicopter is pretty significant even with the engines at idle. When the rotor is brought up to flight rpm before takeoff it is much greater. Ducking and clutching tight your hat or apparel helps deal with this when entering or exiting the helicopter.
With underwing engines, reducing thrust creates a nose-down pitching moment; increasing thrust creates a nose-up pitching moment. The combination of elevator and stabilizer positions also affects pitch. In normal maneuvering, the pilot displaces the elevator by applying an elevator control force.
As the helicopter speed increases, ETL becomes more effective and causes the nose to rise, or pitch up (sometimes called blowback). This tendency is caused by the combined effects of dissymmetry of lift and transverse flow effect.
A: Most helicopters have a main rotor on top of the aircraft and a small rotor on the back of the aircraft. In order to control the helicopter, pilots can tilt the angle of each blade on both rotors, which is called changing the pitch of the blades.
Why is this? Unlike airplanes, helicopters need constant steering and direction on the "cyclic" control stick to stay in the air. Helicopters are designed so that the majority of people's dominant hand can easily rest on the stick at all times.
When the helicopter surpasses its maximum operating envelope, the helicopter becomes incredibly unstable. It is likely to pitch upward and roll to the left. The blades may also stall, causing the helicopter to become powerless.
A proper rotation is important for safety reasons and for minimizing takeoff distance. For example, rotate too early and drag increases, thus increasing the takeoff distance.
Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting. The sensation of “dropping” comes from the retraction of the flaps and slats. The rate of climb is reduced, causing it to feel like a descent.
Therefore, airlines require passengers to open their window shades during takeoffs and landings to allow for eyesight adjustment. It acclimates passengers' eyes to the outside environment so that they can exit the airplane if an emergency occurs.
"If the flight was particularly perilous, you could consider it. But then again the pilots won't hear you as they are not only enclosed within the cockpit but are also still busy completing the landing."
To recover from a stall, the pilot must push the nose down. Then the pilot must increase the engine power using the throttle. When air speed increases again, the pilot can level the wings and pull up to return the aircraft to normal flight.
Landing gear pressure may be alleviated by raising the nose of the aircraft, which increases the angle of attack on the wings and, therefore, slows the plane down. The main landing gear wheels will hit the runway first, followed by the nose gear wheels.
Bright colored clothing may put a reflective glare on the helicopter plexiglass windows and reflect in your photos. Dark clothing helps to eliminate the reflection. Our climate control system keeps our helicopters at a comfortable temperature for the entire flight.
The primary purpose of these headsets is to reduce the noise in the cockpit (they can be very loud) in order to avoid hearing loss (yes, it is that loud) and to facilitate clearer communication with ATC. For quieter airplanes there are in-ear headsets that have more in common with earbuds than the bigger headsets.
No hats, scarfs, or loose items are allowed in the aircraft cabin. Please wear closed-toe shoes. Flip-flops and shoes with open backs are not allowed. Sunglasses are OK to wear as our headset will hold them securely to your head.
Aircraft can take off when the airflow speed over the wing is strong enough to create lift. When the airflow over the wings is disturbed by strong wind gusts, the lift being created is altered. This then causes the wings to flex, creating shudders throughout the aircraft.
During the landing phase, there are 36% of the accidents (14% during the final approach and 22% during landing), accounting for 24% of the fatalities. This means that there is a greater chance of being in an accident during the landing phase but the likelihood of being a fatality is approximately the same.
49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
Historical reasons
According to Ask Captain Lim, this tendency came about due to the nature of early rotary-driven aircraft, such as fighter aircraft from the First World War. It was easier for these aircraft to turn left as this allowed them to follow the torque of their engines.
Bogey, according to Eric Partridge's slang dictionary, is Royal Air Force usage from early in World War II meaning ''an aircraft suspected to be hostile. '' American aviators picked it up from the R.A.F. veterans; in 1945, Newsweek used the term to mean ''in radar code, an unidentified enemy aircraft.
#1 Airport of Lukla, Nepal
This airport was renamed Tenzing-Hillary Airport because the two people conquered Mount Everest for the first time. Here's a list of some special information about this airport. This airport is at an altitude of 2438 meters or 8000 feet.
But to explain it simply, if you get beyond a certain forward speed in a helicopter, your retreating blade suffers from the effects of too low an airspeed, while the advancing blade has problems because its airspeed is too high.
If you're wondering if a helicopter can fly to the top of Mount Everest, the answer is yes. It has been done before – but only once. In 2005, Didier DelSalle flew to the top of and even landed on the 8,848 m (29,030 ft) summit of Mount Everest.
Helicopter operations are much less complex than that of airplanes, but they require a greater skill level and demand more airmanship. Most of a professional fixed-wing pilot's time is spent in the flight levels above FL180 (Flight Level 180; 18,000 feet).
